I am building a Quake3 bsp renderer (Like you didn''t already know with the amount of posts I''ve put out on the subject!!!!). I now wish to implement the visibility stuff so that I can work out what to draw. I have no idea how to do this. I think that I use the bsp tree to work out what leaf I am in, and then use what leaf I am in to work out what leafs can be seen. These should then be rendered. I have no idea what the test is to test visibility, or how to ''walk'' the bsp tree to find out what leaf I am in. I can render the leafs easily if I can work out which is visible. Am I correct with any of this and could you help me with some of the details of this method.
Thx again.
